Hi Everyone; In looking through some of kenwood's info the seem to almost encourage the use of two 20 amp supplies as opposed to one 40 amp supply. I wasn't particularly interested in the 200 watt version so I didn't get into the pluses for two 20 amp supplies but it sounds bulky. Has any tried the 1.8 ssb filter and does it make much of a difference? Has any manual quick start guide etc been posted on I can work this thing.com? Rich
